我编写了基于月份选择显示数据的代码。月份正在改变，但数据没有显示。请参阅我的代码一次并建议我该怎么做。当点击下一个代码时，它会更改月份，但日历中的数据不会显示。 

<!DOCTYPE html>

<form method="post" action="display.php">

<!--<button id="prev">-->
<input type="button" id="prev" name="prev" value="prev" />

//document.getElementById("date").value = new Date().toJSON().slice(0,10)
var today = new Date();
var mm=today.getMonth();
var yy=today.getFullYear();
var monthNames = ["January", "February", "March", "April", "May", "June",
  "July", "August", "September", "October", "November", "December"
];
var dat=monthNames[mm]+' '+yy;
  var yyy="";
document.getElementById("date").value = dat;
document.getElementById('prev').addEventListener("click", function() {
  var last=document.getElementById("date").value;
  var val=last.split(" ");
  var month=val[0];
  var year=val[1];

  if(month=='January'){
    var mmm=11;
    yyy=year-1;
    var dat=monthNames[mmm]+' '+yyy;
    document.getElementById("date").value = dat ;
  }
  else {
    var index=monthNames.indexOf(month);
  var mmm=index-1;
  var dat=monthNames[mmm]+' '+year;
  document.getElementById("date").value = dat;
  }
  });

我通过传递日期值尝试了ajax，但它无效。enter image description here
